SPECIFICATION formingart of Letters Patent No. 663,751, dated December11, 1900.

Application filed eptembcr 6. 1900. Serial No. 29,178. (No model.)

To all 11:71pm it may concern.-

Be it known that we, ARTHUR G. GRENA- MYER and Gnonen A. ROBINSON,citizens of the United States, and residents of Leetonia, in the countyof Columbiana and State of Ohio, have invented a new and ImprovedFilter, of which the following is a full, clear, and exact description.

This invention relates to improvements in filters for oil or otherliquids; and the object is to provide a filter of simple construction inwhich the material may be very rapidly filtered, and, further, toprovide a filter that shall be comparatively cheap to manufacture, thatis not liable to get out of order, and that may be quickly and easilycleaned.

We will describe a filter embodying our invention andthen point out t henovel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a filter embodying our invention. Fig. 2is a top view thereof. Fig. 3 is a vertical section, and Fig. 4 is asection on the line 4 4c of Fig.

The filter comprises a tank 5 for receiving the filtered material.Arranged to be placed on this tank 5 is a receiving vessel 6, havingnear its upper open end a screen 7, and below this screen 7 is ahorizontal partition 8, through which a pipe or tube 9 leads, the saidpipe or tube extending nearly to the bottom of the receiving vessel. Theupper portion of the tank is cut away at one side, and in this cut-awayportion the receiving Vessel is designed to be placed. The receivingvessel is provided with-a stop-cock 10,through which water may bedischarged from the vessel, and it is also provided with water and oilgages l1 and 12. Thetank 5 is also provided with an oil-gage 13 and withan outlet-cock lehthrough which the filtered oil may be drawn oft.

At the upper portion of the taiik is a vacuum-producer consisting of asteam-injector 15, as it is to be understood there shall be apartialvacuum in the tank. Steam for causing the vacuum maybe entered atthe upper end 16 and discharged at the lower end 17 of thevacuum-regulator.

Supported upon the top of the tank and extended into the same at oneside of the receiving vessel is a basket 18 of any suitable material andhaving on its upper end a flange 19, which extends upon the top of thetank, and between this flange 19 and the top of the tank is a rubbergasket 20. A partial vacuum in the tank will cause the basket to beforced down tightly against the rubber gasket, so as to prevent anypossible entrance of air.

Removably placed in the basket 18 is a filter material 21, whichpreferably consists of felt. This is made to correspond substair tiallyto the shape of the basket and is closed at its sides and bottom.

In operation the oil containing water and impurities is poured uponthescreen 7, and this screen will hold or take up all the coarserparticles of dirt or the like, and the oil and water passing upon thepartition 8 will flow through the tube 9 and be separated in thereceiving vessel below the said partition, the oil of course rising tothe top as plainly indicated in Fig. 3. From the receiving vessel theoil is drawn off through the cook 22 and discharged into the filteringdevice 21, through which the oil percolates, leaving the dirt and othermatter in this filter device 21.

When it is desired to filter oil drawn directly from a barrel, it may besiphoned from the barrel into the filtering device 21. The

filterin device 21 ma be renewed, orit ma s y y be removed and readilycleaned when desired, and obviously by removing the basket 18 the tankmay be readily cleaned with water or other suitable material. As thereis a par tial vacuum in the tank 5, there is no danger of the oiloverflowing the basket 18, as it will be forced out of the basket asfast as it can be poured in. In fact, this filter will work as fast asoil and water will separate.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. A filter, comprising a tank, a basketextended into the upper portion of the tank and having a flange portionprojected upon the top of the tank, a packing or gasket arranged betweensaid flange and the top, and a vacuum-regulator connected to the tank,substantially as specified.

2. A filter, comprising a tank, a basket removably supported in theupper portion thereof, a filter material of felt or the like removablyplaced in said basket, and a vacuum-regulator attached to the tank,substantially as specified.

5 3. A filter, comprising a tank, a receiving vessel removably placed onthe tank, a screen in the upper portion of said receiving vessel,

a partition below the screen, and a pipe leading through said partitionand nearly to the 10 bottom of the vessel, substantially as specified.

4:. A filter, comprising a tank, a cup-shaped filter of felt or the likesupported in the upper portion of said tank, a receiving vessel 15supported on the tank, a cock for discharging ARTHUR G. GRENAMYER.GEORGE A. ROBINSON.
